A line with slope 1/2 passes through the point (8, -1). What is the equation of this line?
OverLord2011 [107]
The equation would be: Y= 1/2x-1. Reasoning: Our equation format is Y=mx+b. Consider y to just be there for the mean time, but mx is where we insert our slope. We already know what our slope is in this equation (1/2) so that’s what we’ll insert, changing mx to 1/2x. B is where we put our Y. In this coordinate, our Y is -1 (keep in mind that a coordinate is set up as so: (x,y). Insert all our numbers to replace the variables and you get Y=1/2x-1

Water is leaking out of an inverted conical tank at a rate of 6,500 cm3/min at the same time that water is being pumped into the
Nana76 [90]

Answer:

  285,753 cm³/min

Step-by-step explanation:

The rate of change of volume is the product of the water's surface area and its rate of change of depth.

At a depth of 2 m, the water has filled 1/3 of the 6 m depth of the tank. So, the radius at the water's surface will be 1/3 of the tank's radius of 2 m. The water's surface area is ...

  A = πr² = π(2/3 m)² = 4π/9 m²

The rate of change of depth is 0.2 m/min, so the volume of water is increasing at the rate ...

  dV/dt = (0.20 m/min)(4π/9 m²) = 8π/90 m³/min ≈ 279253 cm³/min

This change in volume is the difference between the rate at which water is being pumped in and the rate at which it is leaking out:

  2.8×10⁵ cm³/min = (input rate) - 6500 cm³/min

Adding 6500 cm³/min to the equation, we get ...

  input rate ≈ 285,753 cm³/min

What is the x value?
Black_prince [1.1K]

Answer:

The correct answer is x = 12.

Step-by-step explanation:

To solve this problem, we must remember that an angle bisector divides the angle into two smaller, equal angles.  This means that we can set the values for each of these smaller angles equal to one another, given that the angle is bisected.  This is modeled below:

9x - 54 = 4x + 6

Now, we can solve this equation like any other.  The first step is to subtract 4x from both sides.

9x - 4x - 54 = 4x - 4x + 6

5x - 54 = 6

Then, we should add 54 to both sides.

5x - 54 + 54 = 6 + 54

5x = 60

Finally, we can divide both sides by 5.

5x/5 = 60/5

x = 12

Therefore, the correct answer is x = 12.

Hope this helps!

Y=9x-9<br> Y=9<br> How do u solve dis ¿-¿
gregori [183]
Subsitute 9 for y
9=y=9x-9
add 9 to both sides
9+9=9x+9-9
18=9x+0
18=9x
divide by 9
2=x


y=9
x=2
